Answer 1

N = int(input())
diamond = []
for i in range(1, N + 1):
    line = ' '.join(['*' for x in range(i)])
    diamond.append(line.center(2 * N, ' ')) 
for i in range(N - 1, 0, -1):
    line = ' '.join(['*' for x in range(i)])
    if i == 1:
        line = line[::-2]
    diamond.append(line.center(2 * N, ' '))
print('\n'.join(diamond))
